DELAMINATION - A separation or splitting of the tape such as separation of the backing into two distinct layers, separation between laminations of a tape consisting of more than one and backing, or the separation between filaments and backing of
a filaments reinforced tape.

DIELECTRIC STRENGTH - The voltage which a tape will withstand without allowing
passage passage of the current through it.

DOUBLE-COATED - The adhesive is applied on both sides of the backing, which
serves principally as a carrier for the adhesive.

ELASTIC MEMORY - A tendency of some tape
backings to attempt to return to their original length after being
elongated.

ELECTROLYTICCORROSION FACTOR - A
measure of the tape’s corrosive effect on a metal conductor.
This is particularly important in selection of tapes for use as electrical insulation.

ELONGATION (Stretch,
ultimate elongation) – The distance a tape will stretch lengthwise before breaking, expressed as a percentage of
original length. Elongation is not necessarily an indication of conformability.

HEAT RESISTANCE - The
ability of a tape to withstand exposure to specified
temperatures after application to a surface. Clean removal after exposure
may or may not be important depending on the intended function of the type of adhesive.

HIGH SPEED UNWIND - The
ability of a tape to withstand exposure to specified temperatures
after application to a surface. Clean
removal after exposure may or may
not be important depending on the
intended function of the tape and the type of adhesive.

HOLDING POWER (Sheer
adhesion) – The ability of a tape to resist the static forces
applied in the same plane as the backing. Usually expressed in time
required for a given weight to cause a given amount of tape to come loose from a vertical panel.
